Edwards, CA – Some interns get coffee. Others might make copies. Not at NASA Armstrong Flight Research Center in California, where a group of students successfully flew a prototype of an aircraft that could one day fly in the Martian atmosphere and send its findings back to Earth.
Called the Preliminary Research Aerodynamic Design to Land on Mars, or Prandtl-M, the small, remotely piloted glider aircraft flew August 11th at Armstrong. It continues an effort that began last year with a mostly different group of students.

Greenbelt, MD – July 2016 was the warmest July in 136 years of modern record-keeping, according to a monthly analysis of global temperatures by scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York.
Because the seasonal temperature cycle peaks in July, it means July 2016 also was warmer than any other month on record. July 2016’s temperature was a statistically small 0.1 degrees Celsius warmer than previous warm Julys in 2015, 2011 and 2009.

Pasadena, CA – In an extensive airborne survey, a NASA-led team has analyzed a previously identified “hot spot” of methane emissions in the Four Corners region of the United States, quantifying both its overall magnitude and the magnitudes of its sources. The study finds that just 10 percent of the individual methane sources are contributing half of the emissions.
Scientists from NASA’s Jet Propulsion Laboratory and Caltech, both in Pasadena, California; the National Oceanic and Atmospheric Administration (NOAA), Boulder, Colorado; and the University of Michigan, Ann Arbor, used two JPL airborne spectrometers to identify and measure more than 250 individual sources of methane.

Pasadena, CA – Following a key program review, NASA approved the Asteroid Redirect Mission (ARM) to proceed to the next phase of design and development for the mission’s robotic segment. ARM is a two-part mission that will integrate robotic and crewed spacecraft operations in the proving ground of deep space to demonstrate key capabilities needed for NASA’s journey to Mars.
The milestone, known as Key Decision Point-B, or KDP-B, was conducted in July and formally approved by agency management August 15th. It is one in a series of project lifecycle milestones that every spaceflight mission for the agency passes as it progresses toward launch. At KDP-B, NASA established the content, cost, and schedule commitments for Phase B activities.

Greenbelt, MD – The low pressure center that has been gyrating over the northeastern Gulf of Mexico for days has now dropped very heavy precipitation over southeastern Louisiana. The Global Precipitation Measurement mission, or GPM, core satellite gathered rainfall data on the system and looked at it in three dimensions.
Up to 10 inches (254 mm) of rain since Thursday, August 11th, has already caused flooding in parts of the state. On August 12th the National Weather Service issued flash flood warnings for many parts of southeastern Louisiana. Much of the New Orleans area is under a flood watch until Saturday morning, August 13th.

Greenbelt, MD – Dark matter, the mysterious substance that constitutes most of the material universe, remains as elusive as ever. Although experiments on the ground and in space have yet to find a trace of dark matter, the results are helping scientists rule out some of the many theoretical possibilities.
Three studies published earlier this year, using six or more years of data from NASA’s Fermi Gamma-ray Space Telescope, have broadened the mission’s dark matter hunt using some novel approaches.

Pasadena, CA – Like cosmic ballet dancers, the stars of the Pleiades cluster are spinning. But these celestial dancers are all twirling at different speeds. Astronomers have long wondered what determines the rotation rates of these stars.
By watching these stellar dancers, NASA’s Kepler space telescope during its K2 mission has helped amass the most complete catalog of rotation periods for stars in a cluster. This information can help astronomers gain insight into where and how planets form around these stars, and how such stars evolve.
NASA research helps develop Artificial Intelligence Technology that may one day help First Responders in the Field

Pasadena, CA – Firefighters have only their wits and five senses to rely on inside a burning building. But research developed in part by NASA’s Jet Propulsion Laboratory, Pasadena, California, may change that, introducing artificial intelligence (AI) that could collect data on temperatures, gases and other danger signals and guide a team of first responders safely through the flames.
AUDREY, the Assistant for Understanding Data through Reasoning, Extraction, and sYnthesis, has received the Undersecretary’s Award for Collaboration from the Department of Homeland Security (DHS) in recognition of its joint development by JPL and DHS.

Pasadena, CA – NASA’s Cassini spacecraft has found deep, steep-sided canyons on Saturn’s moon Titan that are flooded with liquid hydrocarbons. The finding represents the first direct evidence of the presence of liquid-filled channels on Titan, as well as the first observation of canyons hundreds of meters deep.
A new paper in the journal Geophysical Research Letters describes how scientists analyzed Cassini data from a close pass the spacecraft made over Titan in May 2013. During the flyby, Cassini’s radar instrument focused on channels that branch out from the large, northern sea Ligeia Mare.

Greenbelt, MD – Hurricane Earl began as a tropical wave that was tracked by the National Hurricane Center (NHC) from the African coast to the Caribbean Sea. The tropical wave drenched the Dominican Republic, where it was blamed for the deaths of six people.
Southwest of Jamaica on August 2nd, 2016, the tropical wave developed a closed circulation, and Earl was upgraded to a tropical storm.
On August 3rd, Earl became a hurricane when it was located about 150 miles east of Belize. On August 4th Earl made landfall just southwest of Belize City, Belize, at about 2:00am EDT (6:00am UTC).
